Description	The authors explored how microcapsule size and brief exposure affected the bioavailability of five microencapsulated insecticide formulations, chlorpyrifos 23.1 g L-1 CS (Detmol-PRO), chlorpyrifos 20 g L~1 CS (Empire 20), fenitrothion 20 g L_1 CS (Detmol-Mic), cyphenothrin 10 g L~1 CS (Detmol-CAP) and diazinon 30 g L_1 CS (Diacap), to Blattella germanica L. on porous and non-porous surfaces. The hypothesis was tested that microencapsulated (CS) insecticides comprising larger microcapsules show higher efficacy on porous surfaces than formulations with smaller microcapsules.
